IMPROVEMENT IN CMBINATIONfPADLOCKS.

Specification forming part of Letters Patent No. 145,864, dated December 23, 1873; application filed May 23, 1873.

To all whom it may concern:

Be it known that I, WILLIAM N. HALL, of Mexia, in the county of Limestone and State of Texas, have invented a new and useful Improvement in Permutation-Padlocks, of which the following is a speciication:

. The object of my invention is to obtain a padlock in which the permutation locking device is not permanently connected to the hasp; and my said invention consists of a permutation device the iXed ends whereof are provided with sockets to receive the ends of a separate hasp, and be locked therewith by a notched bolt passing through the permutation device and both ends of the hasp, whereby the usual hinged connection of the parts is avoided, and the padlock made more secure and cheaper than when the parts are permanently united.

In the accompanying drawings, Figure 1 represents a view, in perspective, of a padlock with the parts disconnected, and embracing my invention; Fig. 2, a cross-section; Fig. 3, an end view; Fig. 4, a side and end view with the hasp detached; and Fig. 5, the notched bolt detached.

The hasp A has straight dat ends A', both of which are pierced with openings a in line, fora purpose to be presently described. The locking device consists of a series of permutation-rings, B, arranged upon a central spindie, C, between ends D E, one of which, D, forms a part of said spindle, and the other'a nut or screw head, E, to secure and hold the rings upon the spindle. VThe outer faces of these lends are provided with sockets F of a shape and size to receive the flat ends of the hasp, and form a protection thereto when united. The ends D E and the permutationrings have openings b c d corresponding in shape with those, a, in the hasp, and arranged to be adjusted exactly in line when the parts are put together for the reception of a notched bolt, G, which, being inserted in the opening in one end of the hasp, passes through the permutation-rings B and enters the other hasp end, thus securing them together by turning the rings, so that it is not possible to withdraw the hasp from the sockets F of the locking device; and in this way the ends of the notched bolt G fasten the ends of the hasp A within their sockets.

The notches e of the bolt G correspond in number to the rings B; and the latter may be. made in pairs, and united as such by pins, to increase their capacity for changes, which are made in accordance with numbers or letters in a manner well understood.

The center spindle is grooved to receive and hold the bolt G; and, when the parts are secured together by the insertion of the bolt, the rings B are turned so that their openings will be out of line with those in the ends D E, and the projections f of the bolt G will be locked between the rings, so that it cannot be withdrawn until the openings are all again in line.

The sockets F for the hasp ends are provided with shoulders g to make the openings in the ends A of the hasp A and spindle C always match, for the ready insertion of the bolt.

In this as in any permutation-lock, the locking-bolt G can only be withdrawn to separate the parts by a knowledge of the numbers or letters upon which it was locked.

By having the parts separate, I am enabled to fasten the hasp by sliding it over the ends of the locking device directly into guarded seats or sockets F, affording greater security to the lock, making it more economical and convenient for use in the adaptation of a separate hasp for secinity with the Xed ends of a separate locking device.

The openings for the notched bolt are made crosswise, and a mark on the side of the ends D E will indicate the line of the letters upon which the rings are locked-in the instanc shown being the word Hall.77 Y

The notched bolt has a shoulder, h, near one end, to limit its insertion in the lock, and this end forms its handle.

It will be understood that, in changing the number or letters upon which the lock is to be set, the screw-nut is removed, and the rings are changed upon the spindle and shifted so as to obtain a very great number of changes with the separate permutation device.

Having described my invention, I claim- In :L padlock, the separate permutation de- In testimony whereof I have hereunto set vice, constructed with sockets to slide upon my hand, in the presence of two subscribing the ends of the separate hasp, and to be se- Witnesses7 this 14th day of May, A.
